IMPROVED APPARTUS FOR GENERATING GAS.

Specification forming part of Letters Patent N o. 50,548, dated October24, 1865.

To all whom it may concern:

Be it known that I, JOSEPH BAGOT, of the city, county, and State of NewYork, have invented a new and useful Improvement in Apparatus forGenerating Illuminating-Gas and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming part of this specication, inwhich- Figure l is a plan of a bench of gas-retorts with my inventionapplied. Fig. 2 is a transverse Vertical section ofthe same in the planeindicated by the line x :c in Fig. 1. Fig. 3 is a transverse verticalsection in the plane indicated by the line y y in Fig. 1.

lSimilar letters ot' reference indicate corresponding parts in theseveral figures.

The object ot' this invention is to drive the exhausters used inconnection with gas-generating apparatus in an economical manner; and tothis end it consists in obtaining the necessary motive power to drivesuch exhausters from the escaping waste heat Of the retortfurnaces.'Ihis l propose to eect in various ways-for instance, by using the saidheat to heat a steam-boiler for supplying steam to a small steam-enginein connection with the exhauster, or by making the escaping hot gaseousproducts of combustion and heated air from the said furnace drive ahot-air engine in similar connection; butthesimplest method, and thatwhich I have represented in the drawings, is by causing all the saidgaseous products and heated air to pass through and drive a wheel withoblique arms, vanes, or blades of similar character to the sails of awindmill; and'l will now proceed to describe my invention with referenceto the drawings.

A is the retort-setting; B B are the retorts, and G is the furnace. E Eare the pipes leading from the retorts to the hydraulic main F, and G isthe main pipe through which the gas passes from the hydraulic main tothe purifiers. All these parts are or may be similar to thecorresponding parts of gas-generating apparatus in common use.

H is the gas-exhauster, which may be of any known or suitable kind, butwhich is represented as consisting of a reciprocating pum p. It isarranged on the top of the retort bench or setting A, and itspiston-rodI is connected with a crank, J, on a shaft, J, which is arranged insuitable bearings, and which has firmly secured to it a wheel, K, havingobliquefaced arms, vanes, or blades resembling the sails of a windmill;or, in other words, this wheel may be said to be similar to thedrivingwheel of a smoke-jack. This wheel is situated within a casing, L,with which the only outlet, a, from the furnace is in freecommunication, and which is situated at the base of the chimney-stack M,which is the. only outlet from the said casing. rIhe wheel K, its casingL, the outlet a ofthe furnace, and the chimney M are relatively soarranged that all the hot gaseous products of combustion ,and uncombinedheated air escaping from the furnace and ascending by their heat withwhat is termed a natural draft77 pass between the arms, vanes, or bladesof the said wheel on their way to the chimney in such manner that theyproduce the revolution ofthe said wheel and Ot' the crank-shaft, and sogive motion to the exhauster, whichis thereforedriven by the waste-heatfrom the furnace.

What I claim as my invention, and desire to secure by Letters Patent,is-

Obtaining the necessary motive power to drive the exhausters ofgas-generating apparatus for the escaping waste heat of theretortfurnaces, substantially as herein described.
